Placeholders in message_text.

Hi all,

I am using method

CALL METHOD lo_message_manager->REPORT_ELEMENT_ERROR_MESSAGE

                  EXPORTING

                    MESSAGE_TEXT       = 'No flights for &carrid &2 connid'

                    ELEMENT                   = lo_el_connection

                    PARAMS                     = itab

Before this method i am writing code as follows:

               wa-name = 'carrid'.                           * wa is work area

                wa-value = 'connid'.

                APPEND wa to itab.                             *itab is internal table

                wa-name = ls_connection-carrid.          *ls_connection has data which we are entering in the webdynpro view.

                wa-value = ls_connection-connid.

                APPEND wa to itab.

when i enter wrong data No flights for &carrid &2 connid' is displaying in place of carrid and connid i need to get the values.

Please suggest me where i went wrong.

Thanks & regards,

Narsireddy
